adelie (version 1.0.7)

matrix.concatenate: Creates a concatenation of the matrices.

Description

Creates a concatenation of the matrices.

Usage

matrix.concatenate(mats, axis = 2, n_threads = 1)

Value

Concatenation of matrices. The object is an S4 class with methods for efficient computation in C++ by adelie. Note that for the object itself axis is represented with base 0 (so 1 less than the argument here).

Arguments

mats

List of matrices.

axis

The axis along which the matrices will be joined. With axis = 2 (default) this function is equivalent to cbind() and axis = 1 is equivalent to rbind().

n_threads

Number of threads.

    matrix.dense(matrix(rnorm(n * p), n, p))
})
out <- matrix.concatenate(mats, axis=2)
